Abstract.

Searches for pair-production of supersymmetric particles under the assumption that R-parity is violated via a single dominant \(LL{\bar E}\), \(LQ{\bar D}\) or \({\bar U}{\bar D}{\bar D}\) coupling are performed using the data collected by the ALEPH collaboration at centre-of-mass energies of 181–184 GeV. The observed candidate events in the data are in agreement with the Standard Model expectations. Upper limits on the production cross-sections and lower limits on the masses of charginos, sleptons, squarks and sneutrinos are derived.
